CENTRIFUGAL REEL.

:ZPECIFICATION forming part ofLetters Patent No. 326,509, datedSeptember 15, 1885.

Application filed June 25, 1855.

To all whom it may concern.-

Be it known that I, BRUNO KNIFFLER, of Cleveland, in the county ofOuyahoga and State of Ohio, have invented new and useful Improvements inCentrifugal Reels; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvementsin theclass of flour-dressing machines usually known as flour-bolts and theinvention consists in the construction, arrangement, and combination ofvarious parts, all as more fully hereinafter described.

In the drawings which accompany this specification, Figure 1 is aperspective view of my improved machine, showing the rear end thereof.Fig. 2 is a perspective view of the front end. V Fig. 3 is a horizontalsection on the axis of the shaft of the bolting-reel. Fig. 4 is avertical central cross-section. Fig. 5 is a horizontal section on line3/ y in Fig. 4. Fig. 6 is adetached view of the driving-gear and clutch.Fig. 7 is a detached perspective of front and rear of the head whichforms the rear end of the bolting-reel. Fig. 8 is a detail on anenlarged scale. I

. A is the main shaft, running horizontally through the center of themachine, and pro: jecting beyond both ends of the same; and B is thedrive-pulley,secured to either end of the shaft. This shaft is journaledin suitable boxes, to I), supported by the frame of the machine, and hassecured to it the heater-frame O, which is of known construction andoperation.

D and E are the heads of the reel-cylinder; and F is the bolting-cloth,secured to the periphery of these heads and supported between them, soas to form the usual bolting-reel.

In the drawings the bolting-cloth is supported between theheads in thefollowing manner: A cylindrical cage is formed between the two heads bya series of stays, h, to which, at suitable distances apart, theclampsz' are secured, so as to form radial supports for the hoops j,which are secured thereto. The bolting-cloth is made of the propercylindrical shape to fit over the cage, and is secured at its ends inany suitable manner to the heads and (No model.)

also to the loose ring 70, by means of which and the bolts lit is drawntight in the usual manner.

The front head, D, is provided with a hollow hub, c, which is journaledin the boX d, and the rear head, E, has a hollow hub, e, which issleeved upon the shaft A and journaled in a box, f.

G is the spout-box, to which the lower end of the feed-spout is secured.It communicates with the hollow hub c of the head D, and ascrew-conveyer, H, secured upon the shaft A,

conveys the feed from the spout through the hollow hub into the reelafter forcingitthrough 6 5 the wire screen I, which is secured over thedischarge opening.

The spout-box G is adjustably secured to the box d by means of bolts m,passing through circular slots n, (seen better in Fig. 8,) so arrangedthat the spout-box may be adjusted to receive the feedingspout at anyangle that may be most convenient.

The driving-gear is arranged as follows: To the free end of the hub e ofthe head E is secured a gear-wheel, o, and a pinion, p, is secured tothe main shaft A. Upon a countershaft, 1', below the main shaft aresleeved the gear-wheels q s, the former engaging with the pinion p,andthe latter with the gear-wheel 0. To each of the gear-wheels q s issecured one member of a clutch, J, and a lever, K, is arranged to openor close' the clutch by sliding the gear-wheel q laterally upon itsshaft.

A locking devicesuch as the pin t, engaging into suitable holesisarranged to lock the lever K into position to hold the clutch J closedor opened, as desired.

L is a sprocket wheel secured upon the counter-shaft r, and M and N aresprocketwheels secured upon the ends of the shafts of the conveyers O O,which latter are arranged under the reel in the usual manner. An endlesschain, P, passes around the sprocket wheels and conveys motion to theconveyers.

Q is a brush secured at the top of the machine for the purpose ofkeeping the meshes of the cloth open by being broughtin contacttherewith when desired.

A system of cut-offs is arranged below the reel in the following manner:At the lower end of the case, where it discharges into theconveyer-boxes, aseries of slides, R, are arranged alongthe two sides ofthe case, cleats at being secured to the cant-boards between the slidesto hold the latter in position and guide them in opening or closingthem. All the slides may be closed or opened independently of eachother, so that all or any desired portion of each conveyer may be cutoff from access.

The rear head, E, of the reel is provided upon its inner side withpockets S, into which the tailings are scooped by means of the scoops T,and from which the tailings are discharged through the openings 1: intothe dischargespout U. The scoops T are adjustably secured, so that theirfree ends may be brought nearer to or farther from the periphery of thehead; I preferably provide, to this end, the scoops with threaded boltsw, which are secured to'the scoops and project through radial slots atin the head. By means of-thumbnuts z, secured upon the threaded bolts,the

scoops may then be, adjusted radially inor out from the outside, anindicator-scale being provided alongside the slots for the proper guidance of the operator.

The. caseoflthe machineis of the usual description, but is preferablybuilt in sections,

. so as to be readily taken apartfor the purpose of giving ready accessto all the parts to facilitate changes or repairs.

The operation of the machine does not diifer from others of its kind;.but it'presents the following advantages: @First. The adjustablespout-box provides betterfacilities for connecting it with thefeed-spout by allowing it to be directly connected therewith at anyangle.

. Second. The system of cut-ofi is simple and perfect, as the materialcan be-cut off from one conveyer to the other at any point desired, the.adjustment of l the cut-ofls being eifectedinstantaneously by raisingthe hinged .cover of the conveyor-box at either side of Third. Theoutside bolting-cylinder can be stopped at any time without throwing offthe belt. 'Should it become necessary to stop it -for the purpose ofrepairing the cloth, to regulate. the discharge of thetailings, or forany. other purpose, it is only necessary to throw the clutch out of gearby means of the lever K. .When it is considered that the:operation ofthe machine is thus not materially interfered with, and no generalstoppage of other mill machinery need occur on this acr .count, theadvantage of this improvement will readily appear.

, Fourth. The wire screen in the, front head of the reel. forms aneffective disintegrator, which thoroughly loosens the material to bebolted as it passes into the reel.

Fifth. The device for regulating the discharge of the tailings formsalso an important feature, whereby the material can be retained in thereel any length of time found necessary.

Its adjustment to any degree of nicety is simple and easilyeifectediwhile the machine is in operation by first stopping the outsidecylinder by means of the lever K, and then raising the sliding panel atthe tail end of the machine, which gives access to the regulatingdevices which adj ustably secure the scoops. By loosening thethumb-screws and moving the bolts in the slots provided for them thescoops can bernoved from orto thefcloth, care being taken to adjust'themall alike by means of the index. I l
